All linkage problems that I've report you are not a runtime problems.
Your package only failed with our (altlinux) QA tests ...
It's a possible problem in the future.
It's not a problem to fix it now ....

The reason I'm asking is that you will find a problem with every shared library
and plugin that gets linked into the server: libslapd.so and lib*-plugin.so.
The reason we build it that way is because, historically, on some platforms, if
you turn on the linker option to complain about missing symbols, it becomes very
difficult to satisfy all of the linker dependencies in a platform independent
way, which leads to makefiles that are hard to maintain. Platforms we have
supported in the past were aix, tru64, hpux 10, and sgi. It may be that all
modern linkers make this easy to do without lots of kludges in makefiles.
